Australian director Baz Lurhmann recently hinted that he was considering filming The Great Gatsby in 3D, a format that has become a reliable cash cow for the movie industry. TIME looks at other Hollywood attempts to rack in extra dough and extra crowds.

Split Screen

The gimmick: In our digital era, split screen scenes (displaying two or more scenes simultaneously on a partitioned screen) don’t seem like that big of a deal. But the technique was revolutionary when it first came out and was much more difficult to achieve. Filmmakers had to run dual projectors — sometimes even more — synced perfectly for the film to work.

The result: The 1968 flick The Thomas Crown Affair popularized the technique to show multiple parts of the movie’s heist simultaneously. The technique works especially well for the caper movie and modern counterparts like Ocean’s 11 owe a debt of gratitude to Thomas Crown.
